远程抄表系统中嵌入式GPRS无线通信模块的设计与实现

The Design and Implementation of Embedded GPRS Wireless Communication Module in Remote Meter Reading System

集中器作为远程抄表系统电能表和数据中心的一个桥梁,是整个抄表系统数据采集与传输的核心,而其无线通信模块无疑又是这核心中的重点,对整个系统起着控制和枢纽作用,其性能好坏直接影响到系统的通信效率。文章介绍了基于AT89C51RC单片机和无线收发芯片MC55的嵌入式无线通信模块的设计与实现,并给出了硬件设计框图和软件设计流程图。

Centralized device is a bridge between electric energy meter and data center. It is also a core of data collection and transmission in the entire meter reading system, while wireless communication module is undoubtedly the emphases of the core and plays a control and hinge role in the whole system. Its capability directly influences the communication efficiency of the system. This article introduces the design and implementation of embedded wireless communication module based on AT89CS1RC singlechip and wireless transceiver MC55, moreover, its hardware design chart and software flow figures are both provided.
